AI-Powered supplier vetting

SummaryDong Guan Usun Fluid Control Equipment Co., Ltd. is identified as a Chinese trading company with five employees, while other records describe an established factory and five production lines. Its offering focuses on gas booster pumps, air-driven gas boosters, hydro-test pumps, high-pressure systems, and related components. The supplier reports export activity since 2013 and exports representing 90% of total sales, with markets across multiple regions. Peak- and off-season lead times are both stated as within 15 workdays. No management-system certifications are reported, and the quality-control team has fewer than five staff. The company description claims development of a pneumatic booster pump intended to replace a German product and worldwide customer acceptance, but no specific customer cases are provided. Evidence is insufficient to confirm after-sales service or customization capability.

Supplier typeThe supplier is explicitly classified as a trading company, including both the associated-company industry record and the business-entity type. This indicates the entity is primarily trade-oriented, although other records mention manufacturing activities and a factory history.

CertificationsThe supplier reports no certification of management systems (“NIL”). Therefore, the provided evidence does not show possession of management-system certifications.

R&D capabilityThe company description states that it developed a new type of pneumatic booster pump intended to replace a German product, and its listed products include gas booster pumps, high-pressure pump systems, and related components. This supports evidence of product-development activity, although the extent and verification of innovation are not provided.

Production capacityThe records identify five production lines, an 87.0 m² plant, fewer than five quality-control staff, and peak- and off-season lead times within 15 workdays. The supplier also describes a factory established in 2011, but its simultaneous classification as a trading company and limited operating scale indicate production capacity is evidenced but modest.

Product Q&A

Q:What is the maximum air drive pressure?

The maximum outlet pressure is achieved at an air drive pressure of 8 bar (116 PSI). For long life, we suggest keeping the air drive pressure no more than 8 Bar.

Q:Is this pump suitable for underground coal mines?

No, the standard series of boosters are not suitable for underground coal mine applications. USUN does manufacture models for this purpose, but they are distinct from the standard series.

Q:What is the recommended cycle rate for continuous operation?

We recommend a maximum cycle rate of 50-60 cycles per minute for continuous operation. This increases service intervals and helps prevent ice formation at the exhaust.

Q:Does the pump require electrical power?

No, the air-driven models do not require an electrical connection. They are easy to apply with automatic controls and are safe due to the absence of sparks or flames.

Q:How is the outlet pressure controlled?

The outlet stall pressure is easy to set by adjusting the air drive pressure through a simple air pressure regulator. The pump stops automatically when output pressure forces equal the drive force.
